I have, twice now. He doesn't have the voice for it if he's going to scream (which sounds high, comical with voice cracking and all haha). But ive argued this point against the Gosling haters. The people who don't think he's got the voice for it or cuz he's blonde.

A) hair dye
B) Not too much dialogue under the cowl. A whisper like voice, even more subtle than Keaton.

Now, this could only be achieved if people accept that this new Batman may not be the Kevin Conroy approach that they want. We're all expecting a Conroy style of commanding, deep speaking in the mask. I would love that. But we need to stop expecting it because a Gosling like portrayal could be awesome if done right. It could be eerie, the more silent Batman is.
